Abstract
Apparatus and method for securing a heat sink to a heat-generating device on a circuit board. The apparatus clamps onto the heating-generating device and the circuit board in a manner that avoids bending of the circuit board. The apparatus includes a retention module having a plurality of retention features that extend through openings in the circuit board disposed about the perimeter of the heat-generating device, such as a processor. The apparatus also includes a heat sink having a heat sink base for contacting the heat-generating device in order to dissipate heat produced by the device. The heat sink is selectively securable to the retention features of the retention module using levers, such as a wire module, having a spring clip to engage the retention features and clamp the heat sink and retention module together.
